The call sign you start a radio call with is...

• A. Receiver
• B. Caller
• C. Base station
• D. Operator

Answer: (A)

When you start a radio call, you address the recipient first. The receiver’s call sign is spoken at the very beginning so the person or station you want to reach knows the message is intended for them and can pay attention immediately. After you’ve named the receiver, you identify yourself with your own call sign and proceed with the message.

For example, you might say the receiver’s call sign followed by your own, then proceed with “over.” This order ensures the communication is directed and clear from the start. Starting with your own call sign first would delay letting the intended recipient know who’s calling, and terms like base station or operator aren’t the specific recipient you’re trying to contact.
